5. Claims. (Cl. 22B-61.).

The invention relates generally to metallic rieceptacles, and more particularly to the type known as collar cans wherein are provided tear strips adapted to be Wound on keys and by this means torn out of the body lwalls of the cans in order to effect an opening thereof, and it primarily seeks to provide a novel collar structure for such cans.

In cans of the type stated the tear strips usuallyare dened by parallel score lines whichsurround the cans adjacent the upper ends thereof, and a collar is snugly fitted within the upper end of each can. in position for extending upwardly from. the upper extremity of the can body resulting.- from the tearing out of the rip strip, thereby to maintain the desired can body wall height andprovide a support neck over which the skirt or body Wall portion remaining attached to the upper end closure can be telescoped to effect a reclosure of the-can. Such collars usually are formed of metal strips or bands formed into circular shape, and it is desirable to curl or curl and hem the upper and lower edge extremities in orderto avoid pres. entation of raw metal edge portions and also to However in such structures it has been found diiicult to provide the necessary strip or band' end overlap and yet maintain a close fit of al1 parts of the collar against the can body wall and avoid provision of objectionable multiple thickness-bulk at overlapped portions.

Therefore, it is an object ofthe present invention to provide a collar of the character stated in which the strip or bandhas its upper-andlower edge portions curled and hernrned respectively anditsoverlapped upper and lower end edge portionsprovided with inter-fitting tongues and notchescooperating to securely retain the overlapped engagement and avoid provision ofobjectionable multiple thickness at the overlapped portion, and also to provide smooth exterior of the curl Without objectionable external surface projection throughout the circle of the collar and a smooth substantiallycontinuous cylindriform exterior of the collar adapted for snugly engaging-within the container body.

With, the above and other objects in view that will hereinafter appear; the naturev of the invention will bey more clearly understood by reference to the following detailed description, the appended claims, and the several-views illustrated in the ac companying drawing,

In this disclosure the.A invention is illustrated asembodied in a ca-nL including a body 5, a4 lower end closure 6;. and a topend closure l, said clorsures. preferablybein-g; seam-secured on the can body inthe conventional manner;

The.; can body- Ef is provided adjacent its upper end With-A an inwardly directed; rest. bead. 8- prefserably provided as a support for the lower, hem equipped. edgey El ofV the improved collar structure: generally designated ,Mii and which. is equipped withan inwardly directed curl L! at itsiupper-edgeportion. Opposite;v the main. body portion of; the. collar i0? the: can body is; annula-rly-scorect in the conventional manner to; provide a tear` stripI t2; adapted to be 'wound about, a keyr andv torn from:` thev wall. of the canbody: in the; mannerwell; knownin the art for eiecting; opening-of tire.V

According to the invention, the. colla-r.- generally designated l5, is; formed from a, stripvorband of' metal having the` upper and loweredge Portion. of: its ends; shaped; in, the mannerillustrated: in: Figure 2,- it beingunderstoodthatthese: end-s are: brought together andi overlappedA to( provide, the, desired shape of collar intended; to.y snugly llt; within the can body in which the collar is: te be inC orporated;` Whilethese. colla-ra are' most commonly incorporated ini, cylindrical containers, it: is to; bel understood that the collar-structure dis,- closed herein; can beincerboratedil'r oval.; shaped; canbod-ies-or-in: canbodieszotherwise shaped-such as square or oblong structures having; rounded; corners.

Inf the completed cellar structurethe bandends; are overlapped as at la asidcatedin.4 Figures 4, and 5; of' the, drawing, and it, will. be., noted, byreierence toFigureZthat one, end of thebandlat, the. upper edge is, provided with, a plurality of;

spaced notches I4 providing intervening spaced tongues I5 of like width and which are intended to t in spaced notches IB formed in the upper edge portion of the other end of the band and which provide intervening tongues il of like width intended to fit in the previously mentioned notches I4.

It will also be apparent by reference to Figure 2 that the lower edge portion of the band at one end is equipped with a plurality of edge notches I8 providing intervening tongues i9 of like Width intended to engage in spaced notches 2Q formed in the lower edge of the other end of the band and which provide intervening tongues ZI oi the like width intended to engage in the previously mentioned notches it.

When the bands are overlapped in the manner illustrated in Figures l, fi and 5 and the upper edge tongues i5 and il are interlocked in the receiving notches i@ and iii, the edges of said tongues snugly engage at i2 and the lower tongues i9 and 2i interlock in the respective notches 2d and i3 and snugly engage in edge contact as at In this manner the upper edge curl il has substantially smooth exterior Without objectionable external surface projection about the whole circle of the collar in the manner clearly illustrated in Figures l, e, 6 and '7. The hem is formed by folding over the lov-1er edge portion of the band substantially along the dot and dash line indicated at L in said figure. See also Figure 4.

It will be apparent by reference to Figures 4 and 5 of the drawing that the inwardly overlapped band end portion is offset to the extent of its thickness as at 2li thereby to dispose the remainder of the band to snugly engage the body wall of a can in which the collar is inserted throughout the continuity of the collar in the manner clearly illustrated in Figure 5.

It will be apparent that the interlocking tongues I5, il and i9, 2l will secure the overlapped band ends against separation in a circumferential direction, and the folding of the tongue and edge portions of the outermost lapped band and inwardly and upwardly over the innermost lapped band end in the manner illustrated in Figure 6 secures the lapped band ends against separation in the radial direction.

It will be apparent that throughout the ciroumference of the collar a single thickness oi metal is provided except at the two thicknesses provided at the overlapped main body ends and the three thicknesses provided at the position of the interlocked tongues I9, 2l.

While one form of the invention has been shown for purposes of illustration, it is to .be clearly understood that various changes in the details of construction and arrangement of parts may be made without departing from the spirit and scope of the invention as defined in the appended claims.
